This is for either the serious fly tier with an addiction or the novice, as you will have all of the colors required for tying many, many NEW FLIES years to come, at a great discount. 20 - 4 gram bags of each individual color. Enough for a whole fishing season of iridescent and holographic flies. Polaris Flies blended his UVA Pearl 50% WITH the other 19 colors to make it THE MOST light REFLECTIVE anyone could desire TO GET YOUR FLY SEEN! NEW FTM is the best of the newest multi-layered films that fly tying material manufactuters have adapted over the years. It IS NOT "easter basket filler", as that product and all others WILL NOT turn iridescent, just melt into a plastic blob! Customers have used this for over 3 years all over the world, many catching large fish that had proved stubburn to get to strike streamers tied with other less reflective materials. E-Z to work with. NEW FTM is specially cut to 8" legnth and 4-5 times as wide as lesser produicts. I show how easy it is for even teenagers to easily tie fantastically reflective flies.
